Definitions

  • the invention relates to a gusseted bag according to the preamble of claim 1, a method for producing and filling such a gusseted bag and a corresponding FFS machine.
  • the generic filling of sacks is carried out using a wide variety of devices.
  • the sack to be filled is often gripped by a plurality of pairs of gripper tongs during the filling process.
  • FFS Form Fill and Seal
  • a special feature of the way these machines work is the sealing of the bags after the filling process.
  • Such a device is known, inter alia, from DE 199 36 660 A1.
  • a tube section made of thermoplastic plastic with a bottom weld seam is filled with filling material in a filling station.
  • the bags produced by FFS machines are often filled with free-flowing goods. For this reason, too, these sacks are usually not provided with any holes or incisions.
  • a first exception are ventilation openings, which are usually made in a large part of the outer surface of the bag. These openings are designed so that their diameter is no more than one mm in order to prevent the contents from trickling out. So-called micro-perforations have been developed for particularly fine filling goods, which have ventilation holes with diameters that are smaller than 0.2 mm.
  • tear-open perforation is understood to mean a perforation made of incisions or punchings.
  • a tear perforation serves to simplify the tearing of the bag cover.
  • a tearing open of the bag cover in the sense of this publication can also be torn off with parts of the
  • Perforation device assigned to the machine is perforated before the hoses are rewound and this hose reel is fed to the FFS machine.
  • tear perforation in particular forms a weak point through which the filling material trickles.
  • the object of the present invention is therefore to provide a flat or gusseted bag 30, - which was manufactured and filled by an FFS machine and - which is easy to tear open and - which is characterized by lower trickle losses.
  • the present invention is based on the side gusset sacks described and produced and filled in the FFS process and achieves this object in that the sack has a corner weld in the area of at least one corner.
  • the measure according to the invention is - as can be gathered from claim 1 - in the same way for flat sacks.

It should also be noted that the tear-off perforation breaks down into a tear-off perforation with longer perforation incisions 207 and a tear-off perforation with shorter perforation incisions 208.
  • the longer perforation incisions 207 are located in the area between the edge of the bag 209 and the corner weld 206, while the shorter incisions 208 are located in the area between the center line M of the bag 200 and the corner weld 206 of the corner, which is subjected to the tear-off perforation, are located.

  • the tear-off perforation of the sack 214 shown in FIG. 5 is designed differently. Similar to the tear-off perforation of the sack 200, it is composed of a tear-off perforation 207 with long incisions and a perforation 208 with shorter incisions. However, this tear-off perforation is further provided with a perforation 215, which is a tear-off Part of the weld seam 208, which closes the foot end 210 of the sack 214, is permitted. This makes it easier to tear off this part.
  • FIG. 6 A last exemplary embodiment of a sack 217 according to the invention is shown in FIG. 6. Similar to the embodiment with the bag 200, a perforation with long perforation incisions 207 is present in the area between the edge 209 of the bag 217 and the corner weld 206. However, this applies to both corners of the foot region 210 of the sack shown in FIG.
